Good, Authentic Mexican Cookbooks?

Digging into the Serious Eats mailbag, we find this message from a reader asking about Mexican cookbooks. Instead of answering privately and keeping other Serious Eaters out of the loop, we thought we'd post the message here so everyone could benefit. Anyone who cares to chime in may do so! —The Serious Eats Team

Dear Serious Eats,

I am in the market for a good, authentic Mexican cookbook—preferably one with a killer tamale recipe. Have you any suggestions? I've seen a lot that are tailored toward Americans (especially in terms of ingredients), but I would love to find something that, while challenging, will also be worth the effort.
